The Long Count is an astronomical calendar, with each universal cycle lasting 2,880,000 days. The beginning date of the Long Count calendar has been determined to be August 11, 3114 B.C. in the Gregorian calendar, or September 6 in the Julian calendar. The date marks the creation of human beings, according to the Maya.
In the Maya Long Count, the previous world ended after 13 bʼakʼtuns, or roughly 5,125 years. The Long Count’s “zero date” was set at a point in the past marking the end of the third world and the beginning of the current one, which corresponds to 11 August 3114 BC in the proleptic Gregorian calendar.

The Maya had a numeric system, games, aqueducts, and even a calendar to tell time . The calendar that the Maya used looks very different in comparison to the 12 month Gregorian Calendar that we use. The Mayan Calendar consists of three dating systems, which make interpreting the date more unique than our dating system.
The calendar was based on a ritual cycle of 260 named days and a year of 365 days. Taken together, they form a longer cycle of 18,980 days, or 52 years of 365 days, called a “ Calendar Round.”
